Abstract
An acid stable α-galactosidase was produced and purified from mannolytic fungal strain, Penicillium aculeatum APS1. Enzyme was produced using wheat bran and copra cake moistened with corn steep liquor by solid state fermentation. APS1αgal having molecular weight of 65.4 kDa was purified to electrophoretic homogeneity by three phase partitioning and gel permeation chromatography with high enzyme recovery. APS1αgal was found to be maximally active at 55 °C and pH 4.5, having high stability at acidic pH. Thermal stability and thermal inactivation kinetics of APS1αgal were also studied. APS1αgal was found to effectively hydrolyse oligosaccharides as well as polysaccharides having α-1,6 linked galactose. Abolishment of enzyme activity in N-brommosuccinimide revealed an important role of tryptophan residue in catalysis. APS1αgal had shown outstanding tolerance to NaCl and proteases. MALDI-TOF MS/MS analysis indicated that enzyme is probably a member of family GH27. Synergistic interaction between APS1αgal and β-mannanase for hydrolysis of galactomannan was very clear and maximum 2.0° of synergy was found under simultaneous mode of action. This study reports a new source of α-galactosidase with biochemical properties suitable for applications in food and feed industries.

[PMID: 36721204 PMCID: PMC9887927 DOI: 10.1186/s12896-023-00773-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Accepted: 01/20/2023] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Because humans lack α-galactosidase, foods containing certain oligosaccharides from the raffinose family, such as soybeans and other legumes, may disrupt digestion and cause flatulence. RESULTS Aspergillus niger NRC114 α-galactosidase was purified using protein precipitation, gel filtration, and ion exchange chromatography steps, which resulted in a 123-fold purification. The purified enzyme was found to be 64 kDa using the SDS-PAGE approach. The optimum pH and temperature of the purified α-galactosidase were detected at pH 3.5 and 60 ºC, respectively. The pure enzyme exhibited potent acidic pH stability at pH 3.0 and pH 4.0 for 2 h, and it retained its full activity at 50 ºC and 60 ºC for 120 min and 90 min, respectively. The enzyme was activated using 2.5 mM of K+, Mg2+, Co2+, or Zn2+ by 14%, 23%, 28%, and 11%, respectively. The Km and Vmax values of the purified enzyme were calculated to be 0.401 µM and 14.65 μmol min-1, respectively. The soymilk yogurt showed an increase in its total phenolic content and total flavonoids after enzyme treatment, as well as several volatile compounds that were detected and identified using GC-MS analysis. HPLC analysis clarified the enzymatic action in the hydrolysis of raffinose family oligosaccharides. CONCLUSION The findings of this study indicate the importance of A. niger NRC114 α-galactosidase enzyme for future studies, especially its applications in a variety of biological fields.

Purification, biochemical and biophysical characterization of an acidic α-galactosidase from the seeds of Annona squamosa (custard apple). Int J Biol Macromol 2021; 175:558-571. [PMID: 33529636 DOI: 10.1016/j.ijbiomac.2021.01.179] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2020] [Revised: 01/14/2021] [Accepted: 01/28/2021] [Indexed: 02/01/2023]
Abstract
Alpha galactosidase is an exoglycosidase that cleaves α-D-galactose and has numerous applications in medicine, biotechnology, food and pharma industries. In this study, a low molecular weight acidic α-galactosidase was identified from the seeds of custard apple. The purification of α-galactosidase from the crude extract of defatted seeds was achieved by employing ammonium sulphate fractionation, hydrophobic interaction and gel filtration chromatographic techniques. The purified custard apple α-galactosidase (CaG) migrated as a single band in native PAGE corresponding to molecular weight of ~67 kDa and cleaved chromogenic, fluorogenic and natural substrates. CaG was found to be a heterodimer with subunit masses of 40 and 30 kDa. The kinetic parameters such as KM and Vmax were found to be 0.67 mM and 1.5 U/mg respectively with p-nitrophenyl α-D-galactopyranoside. Galactose, methyl α-D-galactopyranoside and D-galacturonic acid inhibited CaG activity in mixed mode. The CD spectral analysis at far UV region showed that purified CaG exists predominantly as helix (35%), beta sheets (16.3%) and random coils (32.3%) in its secondary structure. These biochemical and biophysical properties of CaG provide leads to understand its primary sequence and glycan structures which will eventually define its novel physiological roles in plants and potential industrial applications.

Mar Drugs 2018; 16:E349. [PMID: 30250010 PMCID: PMC6213131 DOI: 10.3390/md16100349] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Revised: 09/20/2018] [Accepted: 09/21/2018] [Indexed: 12/03/2022] Open
Abstract
A novel wild-type recombinant cold-active α-d-galactosidase (α-PsGal) from the cold-adapted marine bacterium Pseudoalteromonas sp. KMM 701, and its mutants D451A and C494N, were studied in terms of their structural, physicochemical, and catalytic properties. Homology models of the three-dimensional α-PsGal structure, its active center, and complexes with D-galactose were constructed for identification of functionally important amino acid residues in the active site of the enzyme, using the crystal structure of the α-galactosidase from Lactobacillus acidophilus as a template. The circular dichroism spectra of the wild α-PsGal and mutant C494N were approximately identical. The C494N mutation decreased the efficiency of retaining the affinity of the enzyme to standard p-nitrophenyl-α-galactopiranoside (pNP-α-Gal). Thin-layer chromatography, matrix-assisted laser desorption/ionization mass spectrometry, and nuclear magnetic resonance spectroscopy methods were used to identify transglycosylation products in reaction mixtures. α-PsGal possessed a narrow acceptor specificity. Fructose, xylose, fucose, and glucose were inactive as acceptors in the transglycosylation reaction. α-PsGal synthesized -α(1→6)- and -α(1→4)-linked galactobiosides from melibiose as well as -α(1→6)- and -α(1→3)-linked p-nitrophenyl-digalactosides (Gal₂-pNP) from pNP-α-Gal. The D451A mutation in the active center completely inactivated the enzyme. However, the substitution of C494N discontinued the Gal-α(1→3)-Gal-pNP synthesis and increased the Gal-α(1→4)-Gal yield compared to Gal-α(1→6)-Gal-pNP.

Abstract
A novel α-galactosidase of glycoside hydrolase family 36 was cloned from Bacillus coagulans, overexpressed in Escherichia coli, and characterized. The purified enzyme Aga-BC7050 was 85 kDa according to SDS-PAGE and 168 kDa according to gel filtration, indicating that its native structure is a dimer. With p-nitrophenyl-α-d- galactopyranoside (pNPGal) as the substrate, optimal temperature and pH were 55 °C and 6.0, respectively. At 60 °C for 30 min, it retained > 50% of its activity. It was stable at pH 5.0–10.0, and showed remarkable resistance to proteinase K, subtilisin A, α-chymotrypsin, and trypsin. Its activity was not inhibited by glucose, sucrose, xylose, or fructose, but was slightly inhibited at galactose concentrations up to 100 mM. Aga-BC7050 was highly active toward pNPGal, melibiose, raffinose, and stachyose. It completely hydrolyzed melibiose, raffinose, and stachyose in < 30 min. These characteristics suggest that Aga-BC7050 could be used in feed and food industries and sugar processing.

Abstract
A monomeric α-galactosidase (ILGI) from the mushroom Irpex lacteus was purified 94.19-fold to electrophoretic homogeneity. ILGI exhibited a specific activity of 18.36 U mg(-1) and demonstrated a molecular mass of 60 kDa in sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). ILGI was optimally active at 80 °C and pH 5.0, and it was stable over a temperature range of 4-70 °C and a wide pH range of 2.0-12.0. ILGI was completely inactivated by Ag(+) and Hg(2+) ions and N-bromosuccinimide (NBS). Moreover, ILGI exhibited good resistance to proteases. Galactose acted as a noncompetitive inhibitor with Ki and Kis of 3.34 and 0.29 mM, respectively. The α-galactosidase presented a broad substrate specificity, which included p-nitrophenyl α-D-galactopyranoside (pNPGal), melibiose, stachyose, and raffinose with Km values of 1.27, 3.24, 7.1, and 22.12 mM, correspondingly. ILGI exhibited efficient and complete hydrolysis to raffinose and stachyose. The aforementioned features of this enzyme suggest its potential value in food and feed industries.

Abstract
α-Galactosidases are of great interest in various applications. A glycoside hydrolase family 27 α-galactosidase was cloned from Pontibacter sp. harbored in a saline soil and expressed in Escherichia coli. The purified recombinant enzyme (rAgaAHJ8) was little or not affected by 3.5-30.0% (w/v) NaCl, 10.0-100.0 mM Pb(CH3COO)2, 10.0-60.0 mM ZnSO4, or 8.3-100.0 mg mL(-1) trypsin and by most metal ions and chemical reagents at 1.0 and 10.0 mM concentrations. The degree of synergy on enzymatic degradation of locust bean gum and guar gum by an endomannanase and rAgaAHJ8 was 1.22-1.54. In the presence of trypsin, the amount of reducing sugars released from soybean milk treated by rAgaAHJ8 was approximately 3.8-fold compared with that treated by a commercial α-galactosidase. rAgaAHJ8 showed transglycosylation activity when using sucrose, raffinose, and 3-methyl-1-butanol as the acceptors. Furthermore, potential factors for salt adaptation of the enzyme were presumed.

Abstract
α-d-Galactosidases (EC 3.2.1.22) are enzymes employed in a number of useful bio-based applications. We have depicted a comprehensive general survey of α-d-galactosidases from different origin with special emphasis on marine example(s). The structures of natural α-galactosyl containing compounds are described. In addition to 3D structures and mechanisms of action of α-d-galactosidases, different sources, natural function and genetic regulation are also covered. Finally, hydrolytic and synthetic exploitations as free or immobilized biocatalysts are reviewed. Interest in the synthetic aspects during the next years is anticipated for access to important small molecules by green technology with an emphasis on alternative selectivity of this class of enzymes from different sources.

Abstract
A novel β-galactosidase from Lactobacillus plantarum (LPG) was over-expressed in E. coli and purified via a single chromatographic step by using lowly activated IMAC (immobilized metal for affinity chromatography) supports. The pure enzyme exhibited a high hydrolytic activity of 491 IU/mL towards o-nitrophenyl β-D-galactopyranoside. This value was conserved in the presence of different divalent cations and was quite resistant to the inhibition effects of different carbohydrates. The pure multimeric enzyme was stabilized by multipoint and multisubunit covalent attachment on glyoxyl-agarose. The glyoxyl-LPG immobilized preparation was over 20-fold more stable than the soluble enzyme or the one-point CNBr-LPG immobilized preparation at 50 °C. This β-galactosidase was successfully used in the hydrolysis of lactose and lactulose and formation of different oligosaccharides was detected. High production of galacto-oligosaccharides (35%) and oligosaccharides derived from lactulose (30%) was found and, for the first time, a new oligosaccharide derived from lactulose, tentatively identified as 3'-galactosyl lactulose, has been described.
